22 Jun 1999 | | Journal: | Physical Review A 60, 4301 (1999) | | Subject: | Optics | physics.optics | | Abstract: | A moving dielectric appears to light as an effective gravitational field. At low flow velocities the dielectric acts on light in the same way as a magnetic field acts on a charged matter wave. We develop in detail the geometrical optics of moving dispersionless media. We derive a Hamiltonian and a Lagrangian to describe ray propagation. We elucidate how the gravitational and the magnetic model of light propagation are related to each other. Finally, we study light propagation around a vortex flow. The vortex shows an optical Aharonov--Bohm effect at large distances from the core, and, at shorter ranges, the vortex may resemble an optical black hole. | | Source: | arXiv, physics/9906038 | | Services: | Forum | Review | PDF | Favorites | |
